You need to do a compression check, oil soaked plugs isn't good. Do you have forged pistons or? And...what was your ring end gap? I'd hate say you may have broken rings, that's pretty drastic; were all cylinders oil soaked?

If it were me, I'd like what carsavvycook thinks. My thoughts are worst case.

Good luck, Larry
